Scale Drawing of 35mm & 120/220 negative sizes

[divewizard]

I have several Realist (5 perforation) and European (7 perforation) stereo cameras who's negative sizes are not included in other film size comparisons I have seen. For that and getting a true feel for the differences in negative sizes I made the following scale drawing. I hope you find it useful as well.

Thanks for posting this, Chris, very helpful.

I don't know about the other sizes but both 6x9 and 6x12 exhibit some variation in their actual sizes from brand to brand. This may or may not be important in showing relative sizes, but may be more important for people looking at lens coverage of gate sizes on transparencies and projectors.

I think that the dimensions are nominal, essentially as previously noted. The actual size of camera openings and, hence, the actual size of the negative area can vary slightly. Nevertheless, this is a nice comparison. Thanks.
